Many Flowered Aster
That’s actually the name of this particular autumn aster; I guess they ran out of creative ideas in naming the dozens of little white composite flowers with their raised warm yellow centers. I’m a pushover for little white flowers, especially when they are gently touched by morning sun against a backdrop of weathered wood.
Most asters have flowers only at the end of the stem, or they bloom in succession along the stem, but this particular aster also has many branches, each with their own sets of flowers, and when they bloom all at once the plant looks very snowy; this is probably the origin of the term “many-flowered”. Here is last year’s photo entitled “Many Flowered Aster”.
